The Standard Model and Beyond, Second Edition, presents an advanced introduction to the physics and formalism of the standard model and other non-abelian gauge theories. It provides a solid background for understanding supersymmetry, string theory, extra dimensions, dynamical symmetry breaking, and cosmology. The book covers the development of the technology of particle physics, including Feynman diagrams and relevant group theory. The first edition was highly praised. This second edition brings the physics up to date after the first run of the LHC, and includes new material on the Higgs boson; neutrino mass and mixing; collider physics; dark matter; flavor physics; and electroweak physics.
